A quilted throw is a different object from a fleece one. It has layers, so it has weight, and it holds its shape when folded instead of collapsing into a heap on the arm of a chair. Dorothy is Trudie's blue print, worked with embroidery, which means the pattern carries actual texture you can run a hand over rather than a flat printed surface.
That texture is why it looks good even when nobody is using it. Fold it over the back of a reading chair, drape it across the foot of a bed, or leave it in a basket beside the sofa and it reads as part of the room rather than as laundry. It is also the throw blanket somebody actually reaches for during a film, which matters rather more than how well it photographs. If you already own a solid throw, this is the one that adds the pattern; if you own several patterns, the embroidery gives it enough texture to sit beside them.
How do you wash a quilt? Quilts are generally washed cold on a gentle cycle with a mild detergent and dried on low heat, since hot water and high heat can shrink cotton batting and set permanent creases. Washing a quilt on its own rather than in a full load keeps the stitching from being stressed by other items tumbling in the drum.
